How to Fix CVE-2026-89848

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-89848, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Quiesce response IRQ before freeing request queue qla2xxx_delete_qpair() deletes the request queue before the response queue. qla25xx_delete_req_que() frees the request queue memory (kfree(req) in qla25xx_free_req_que()), but the response-queue MSI-X is only released later, in qla25xx_free_rsp_que(). In that window the response interrupt can still fire, qla2xxx_msix_rsp_q() queues qpair->q_work, and qla_do_work() -> qla24xx_process_response_queue() dereferences the now-freed rsp->req (LOGINOUT/CT/ELS entries and the status path), a use-after-free. The cancel_work_sync() added for the qpair teardown lives in the response free path, which runs after the request queue is already freed, so it does not protect rsp->req. Release the response-queue interrupt and flush qpair->q_work before deleting the request queue, so no late completion can reach the freed request queue. Clearing have_irq makes the subsequent qla25xx_free_rsp_que() skip its free_irq(), and the firmware queue-delete order (request then response) is preserved; the request-delete mailbox completes on the default vector and is unaffected by dropping the qpair response interrupt early.
